Question

1. Factorise the following expressions:
(i) 16x2 + 24xy + 9y​

Answer 1

Answer:

We know 16x 2+24xy+9y 2

=(4x)

2

+2(4x)(3y)+(3y)

2

We know appropriate identities is x

2

+2xy+y

2

=(x+y)

2

Here x=4x and y=3y

Thus (4x)

2

+2(4x)(3y)+(3y)

2

=(4x+3

Answer 2

Answer:

=24xy+9y+32

Step-by-step explanation:

=16 \times 2 + 24 x y + 9 y

Multiply 16 and 2 to get 32.

=32+24xy+9y

=24xy+9y+32
